CROSS REFERENCE TO RELATED APPLICATION

This application claims priority under 35 USC §119 to Finnish Patent Application No. 20145012 filed on Jan. 8, 2014, which application is hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The present invention relates to packages for cartridges of firearms having a container element filled with a number of cartridges.

BACKGROUND OF THE INVENTION

Packages for cartridges of firearms typically comprise a container element filled or fillable with a given number of cartridges, and at least one closure element for the container element. In cartridge packages the container element typically consists of a simple box and the closure element is formed of a cover which can be swung by folding or is removable by pulling out. The cartridges are arranged in the box either loosely or in a holding element such as, for instance, a honeycomb frame. A label with information about the cartridges is typically attached to the outside of the container element. The information on the label comprises for example caliber, information of bullet type, code, weight, game, velocity, length of barrel, energy, trajectory, etc. The information can also be directly printed on the surface of the container element. Trajectory of the bullet of the cartridge type contained in the container element is typically presented in a trajectory table indicating the trajectory of the bullet at given distances in the calibrating adjustment temperature, typically +20° C.

Among other things such as gravity, wind, humidity, and elevation, temperature also has an effect to the trajectory of the bullet. The air temperature and the temperature of the powder are the main influencing factors in the temperature effect to the trajectory of the bullet. FIG. 1 shows an example of the temperature effect on bullet trajectory. As can been seen for longer distances, the effect increases and especially in game hunting where the shooting distance is longer, the temperature effect is significant in respect of the shooting accuracy and thus to success of shooting. Thus when shooting in temperatures not corresponding to the calibrating adjustment temperature, the trajectory will not be as desired as the information needed for temperature correction is not available.

SUMMARY OF THE INVENTION

An object of the present invention is to create a package for cartridges of firearms by which the above described problem relating to the need for information regarding the temperature effect on the bullet trajectory is eliminated or at least minimized.

Another object of the present invention is to create a new type of presenting information of temperature effect on the bullet trajectory.
